I recently upgraded from 3.0.19205 to 3.4.20196 without any problems on my 2019 Expedition. I did customization with AsBuilt codes - again no issues.
Here’s my question. On my son’s 2020 Expedition, his Sirius XM display looks different (he is running 3.4.20136.) For example, the preset buttons display logos, his screen displays album art, and he has the < channel > channel browsing controls at the top of the screen. I did not update my APIM firmware. What must I do to get the same Sirius display as is on my son’s Expedition?
